This works. It fades the label to invisibility.
label.alpha = 1.0;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.5];
label.alpha = 0;
[UIView commitAnimations];
and so does this,
label.alpha = 1.0;
[UIView animateWithDuration:2.5 animations:^{label.alpha = 0.0;} ];
The documentation says the latter is now preferred and does the same thing as
the former. In particular, both will
start a separate thread for the animation.
My problem is that the second method seems to block the main thread. While it
is acting I cannot use any of the controls on the screen. The first method lets
me do what I wish as it proceeds.
Anyone have advice?
thanks,
David
